Hello and thanks for your precious feedback!
I can tell you backlinks and a quick opener are projects we want to tackle after 2.0 release.
I do have some questions/considerations about the other proposals
Uncreated notes
I have some problem with the concept of uncreated note and way more with creating notes without an explicit user intention. The first creates a new note state (linked but not created) and this has to be communicated in the completion panel. I can’t think of a good way to achieve this without writing “Note not created” somewhere near the title (not a good solution). On the other hand creating notes while writing wiki links makes we wonder what should happen when a link is edited: Should Bear create another note with the fixed title, delete the previously created, so keep track of the created but not used notes somehow. Also, might be me but, triggering app actions while editing the text feels like possibly going against user expectations and intentions.
I do wonder if this can be mitigated by a better way to move back and forth notes in a way creating a new note with a click is friction less.
Auto tag notes created with wiki links
This seems very functional to the way you use tags and wiki links but feels unexpected. New notes created with a tag selected in the sidebar do report the tag, but the same wiki link can be clicked in different context (Notes, Trash, Archive, detached windows, …) and users might not see the selected tag in the sidebar.
Unlinked mentions
I can see obsidian have those but I wonder what they are used for, can you give your use case? Also, are they always meaningful? As far as I can see they are just text matches of the current note title, but if the title is something simple (e.g. “hello”) don’t you get a lot of unwanted/unuseful results?
Block references and transclusion
I don’t think these features will come to Bear. I understand and like it’s power but transclusion makes sense if the whole app is built around it and we want to stick to the “just text” idea. This unfortunately makes also very hard to make block references because we lack of identifiers for each paragraph in the text.
A graph of links
This too feels a little out of place for an app like Bear but luckly some third party developers managed the created those graph from Bear’s database.
